Intel Stock Crashes Up to 30% After Weak PC Forecast

Intel shares fell as much as 30% in the session after the company released third-quarter 2026 results, a drop that Yahoo Finance, Yahoo Finance UK, Benzinga, Reuters and Breitbart all described in similar terms: the chipmaker's worst single trading day since 1974. The decline came even though Intel pointed to rapid growth in AI-related chip demand, because the company's forward guidance flagged continued weakness in the PC market that investors judged more important than the AI tailwind.

What happened

Reuters reported, via Investing.com, that Intel's warning "sparks chip rout as PC weakness clouds turnaround," linking the sell-off directly to the company's outlook rather than to the quarter it had just reported. Benzinga reported that Bank of America downgraded Intel's stock rating as shares headed toward what it called their worst day since July 1974, and tied that call to the same earnings reaction. A separate Yahoo Finance report framed the apparent contradiction at the center of the story: Intel's AI chip business grew 78%, yet the stock still fell roughly 30% once the PC-market guidance became the market's focus.

None of the reporting reviewed for this article included a primary-source link to Intel's own third-quarter 2026 earnings release or 8-K filing with the Securities and Exchange Commission, so the exact revenue, earnings-per-share and fourth-quarter guidance figures behind the move could not be independently verified for this piece. Readers should treat the "beat on earnings, miss on outlook" framing used in initial wire coverage as reported, not as independently confirmed against Intel's own filing.

The numbers, as reported

Why the reported percentage drops don't match

Four outlets covering the same event cited four different decline figures, ranging from 25% to roughly 30%. That spread is common after a volatile earnings reaction and typically reflects when a figure was captured: premarket trading, an intraday low, or the final closing price can all differ meaningfully for a stock swinging this sharply in a single session. None of the reports reviewed specified whether their percentage was measured against the prior close, an intraday high, or a premarket quote, so this article cannot reconcile the figures to one authoritative number. What is consistent across every account is the comparison point: multiple outlets independently described the move as Intel's steepest single-day drop since 1974, which is a different and more specific claim than the "worst in 50 years" language used in some headlines, since 1974 is exactly 52 years before this report.

This has happened to Intel before

This is not the first time a single trading session has produced that framing. CNBC reported that Intel suffered its worst day on Wall Street in 50 years on August 2, 2024, when shares fell to their lowest price in over a decade following a different earnings report. That episode also triggered declines across global chip stocks including TSMC and Samsung, according to CNBC's reporting at the time. The repetition of the "worst in decades" description for two separate events roughly two years apart underscores how much Intel's stock has swung on earnings reactions during its ongoing turnaround effort, rather than establishing that the October 2026 move was historically larger than the 2024 one — this article did not verify the exact percentage decline from the 2024 event to compare the two directly.

What's still unknown

Several questions remain open based on the reporting reviewed. The precise revenue and earnings-per-share figures Intel reported for the third quarter of 2026, and the specific fourth-quarter guidance range that triggered the sell-off, were not available in a primary filing checked for this article. It is also not established, from stock-price movement alone, whether Bank of America's downgrade or the guidance itself was the larger driver of the decline, since both became public around the same time. Readers who want the underlying figures should look for Intel's own earnings release and 8-K filing with the SEC, which would show the exact reported results and management's stated guidance rather than a market reaction to them.
